Thank you so much Charlotte for your help. I've made tons of scarves and afghans but this is my first more advanced project. I cant wait to get back at it. This is also my first post to this forum and I think I'm going to like it here!

Is the reversible lace rib a multiple of 4? If so I think any multiple of 4 would work with the pattern.

Thank heaven for the ability to enlarge pictures on my iPad! And for the other project on Rav that let me clearly see it's a tam.

I could be wrong, but with a 90 stitch cast on, a multiple of 4 for the reversible lace rib doesn't work mathematically, but a multiple of 5 or 10 could. Not knowing how the designer planned the increases, then the decreases for the tam, I figured sticking with a rib that accommodates the number of stitches in the cast on might be the easiest work around if the stitch count for the cast on is accurate in the pattern.

It's also equally likely that the cast on for the larger size was miscounted and should really be be 88. Like I've never done that before...

You're more than welcome.

However, you may want to figure out the multiple of the lace pattern by adding up the number of stitches in the repeat. If its a multiple of 4 as GG asked about (BTW, she's our resident yarn whisperer ), you might want to try a CO of 88, or contact the designer.

Welcome to the best knitting corner on the web!

Yarn whiperer? OMG scare me away, why don't'cha?

Are there corrections for the pattern?
Can you contact the designer?
Are there pages on Ravelry where people have discussed this issue?

You could post a few lines from the pattern, I'd think the first row after the rib if it includes increases would be helpful. Don't post the whole pattern or even a large chunk of it due to legal issues. Knowing just exactly what the lacy rib pattern is would help.

You've gotten lots of good suggestions. You could also work the 2x2 rib in the round over 88sts and then increase on the last round to 90 for the lace pattern. See if the stitches increase anyway as you transition from rib to body of the hat.
